How to bake brick-wall geomerty into texture image?
There's An Easy way to Bake a Normal Map from High Poly Mesh (Your Wall) To a low poly simply a cube.The first thing you would have to do. Is place High Poly Mesh in First Layer &amp; Lowpoly in Second.


I hope you'd be using Cycles Rather than Internal its just a slight difference.





In UV Image Editor Click for Image > New Image. Select a relation accordingly (make Sure it will be the power of 2) The Higher Resolution will give better Result.




Black Image Should Appear


Select the Both Mesh High-Poly (Inactive) Low-Poly (Active). Select High Poly First &amp; Lowpoly then(so High Poly will be inactive &amp; Lowpoly Active) (Remember with Both layer Active).





Last one Open Node Setup add a material for the Mesh (if it don't have one). Add Texture Node Don't Connect this node to the shader instead browse the Black Image which was created in UV Image Editor.




Bake It. (I will Edit the answer &amp; will Post the Result later. I was in a Hurry) Sorry :(
